(section: ADD_note)
Note Icon 注マーク The functions whose names end with _ADD return the same results as the corresponding Microsoft Excel functions. Use the functions without _ADD to get results based on international standards. For example, the WEEKNUM function calculates the week number of a given date based on international standard ISO 8601, while WEEKNUM_ADD returns the same week number as Microsoft Excel.
名前の最後が _ADD である関数は、対応する Microsoft Excel 関数と同じ結果を返します。国際標準に基づく結果を取得するには、_ADD のない関数を使用します。たとえば、WEEKNUM 関数は国際標準 ISO 8601 に基づいて与えられた日付の週番号を計算しますが、WEEKNUM_ADD は Microsoft Excel と同じ週番号を返します。(par_idN10600.)

Office internally handles a date/time value as a numerical value. If you assign the numbering format "Number" to a date or time value, it is converted to a number. For example, 01/01/2000 12:00 PM, converts to 36526.5. The value preceding the decimal point corresponds to the date; the value following the decimal point corresponds to the time. If you do not want to see this type of numerical date or time representation, change the number format (date or time) accordingly. To do this, select the cell containing the date or time value, call its context menu and select Format Cells. The Numbers tab page contains the functions for defining the number format.
内部的には、Office は日付または時刻の値を数値として処理します。日付または時刻の値に書式「数値」を設定すると、この値は「日付値」という数値に変換されます。たとえば、01/01/2000 12:00 PM に書式「数値」を設定すると、36526.5 という日付値になります。整数部分は日付に相当し、小数部分は時刻に相当します。このような日付または時刻の表記を見たくない場合は、日付または時刻の書式を変更します。日付または時刻の書式を変更するには、日付または時刻の値が入っているセルを右クリックして、表示されたコンテキストメニューから セルの書式設定 を選択します。見出しページ には、数の書式を定義する機能があります。(par_id3150437.170)

Date base for day zero
日付ゼロの日付ベース(hd_id2408825.)

Dates are calculated as offsets from a starting day zero. You can set the day zero to be one of the following:
日付は、開始日ゼロからのオフセットとして計算されます。 日付ゼロを次のいずれかに設定することができます。(par_id9988402.)

Warning Icon 警告マーク When you copy and paste cells containing date values between different spreadsheets, both spreadsheet documents must be set to the same date base. If date bases differ, the displayed date values will change!
日付値が入ったセルを異なる表計算ドキュメント間でコピー&ペーストする場合、両方の表計算ドキュメントが同じ日付ベースに設定されていなければなりません。 日付ベースが異なると、表示される日付値が変わってしまうことに注意してください。(par_id1953489.)

In (in case of MAC)Office - Preferences(/in case of MAC)(in other case)Tools - Options(/in other case) - Office - General you find the area Year (two digits). This sets the period for which two-digit information applies. Note that changes made here have an effect on some of the following functions.

Note Icon 注マーク When entering dates, slashes or dashes used as date separators may be interpreted as arithmetic operators. Therefore, dates entered in this format are not always recognized as dates and result in erroneous calculations. To keep dates from being interpreted as parts of formulas, place them in quotation marks, for example, "07/20/54".
日付を入力するとき、日付の区切り記号として使用するスラッシュ記号またはダッシュ記号が算術演算子として認識される可能性があります。つまり、この書式で入力する日付が日付として認識されない場合、計算結果も正しくなくなります。数式に入力する日付を日付として正しく認識させるには、"54/07/20" や "54-07-20" のように、日付を引用符で囲んでください。(par_id3150654.185)
